Abstract
Nowadays it is common practices to strengthening the soft subgrade by using waste materials. Granulated blast furnace slag (GBFS), an industrial waste may be used to stabilize soft clay sub-grade. In the present study, an attempt has been made to evaluate the effect of GBFS contents on California bearing ratio (CBR) value of clayey soil GBFS mixture. Three types of clayey soil and one types of GBFS has been used in the present investigation. Soaked CBR test has been performed with varying GBFS content (0–50%) for above three types of soil. From the experimental outcomes it has been found that with increase in GBFS content the soaked CBR values increases and reaches a maximum value at certain GBFS content after that it decreases. The optimum value of GBFS content is 30% irrespective of types of soil when it has been compacted at OMC and MDD of the respective mixture. Based on the experimental data a nonlinear power model has been developed to predict the CBR value of soil GBFS mixture in terms of GBFS content and CBR value of the respective soil alone.
